12 P. GLABRIFOLIA (D. C. 1. c. and mem. par. t. 5.) stems 

 erect, branched, suffruticose ; branches pubescent ; leaves gla- 

 brous, oblong-linear, bluntish, twice the length of the stipulas ; 

 cymes terminal, dense, many-flowered, in crowded heads. Tj . ? 

 2/ . ? S. Native of Sierra Leone. This species differs from P. 

 tenuifolia in the leaves not being subulate, nor keeled, nor with 

 revolute edges ; in the stipulas being large, and in the flowers 

 being capitate. 



Glabrous-leaved Polycarpsea. PL 1 foot. 



13 P. LiNEARirbuA (D. C. 1. c. and mem. par. t. 6.) stems 

 erect, or somewhat ascending at the base, branched ; branches 

 pubescently hairy ; leaves linear, elongated, pubescent, 3 times 

 longer than the stipulas ; cymes crowded into a dense terminal 

 roundish head. 0. F. Native of Senegal. Paronychia lineari- 

 folia, D. C. in Lam. diet. 5. p. 26. Illecebrum linearifolium, 

 Pers. ench. 1. p. 261. Alternanthera erecta, Rchb. in Sieb. pi. 

 exsic. seneg. no. 60. Habit of Celosia, but the characters are 

 those of Polycarpcea. 



Linear-leaved Polycarpaea. PL 1 foot. 



14 P. FRANKENIOIDES (Presl. in Hoenk. reliq. 2. p. 6.) stems 

 much branched, diffuse, procumbent, roughish ; branches oppo- 

 site ; leaves opposite, oblong, obtuse, clothed with rough pubes- 

 cence ; flowers in dichotomous corymbose panicles ; sepals blunt- 

 ish, pilose. . H. Native of the Island of Luzon. 



Frankenia-like Polycarpasa. PL procumbent. 

 \ Species not sufficiently known. 



15 P. CARNOSA (Chr. Smith in Buch. can. p. 142.) stem 

 shrubby ; leaves 6 in a whorl, fleshy : lower ones spatulate : 

 upper ones lanceolate ; stipulas very short, jagged. Jj . G. Na- 

 tive of the Canary Islands. 



Fleshy Polycarpeea. Shrub -j foot. 



16 P. SMI'THII (Link in Buch. can. p. 142.) leaves 6 in a 

 whorl, linear, glabrous, obtuse ; stipulas very short ; panicle 

 dichotomous ; branchlets divaricate ; bracteas ovate, shorter 

 than the calyx. J? . G. Native of the Canaries, in the island 

 of Palma, at Cumbre de Caldera. Very nearly allied to P. stel- 

 Idta but differs in the panicle. 



Smith's Polycarpaea. PL -j- to \ foot. 



1 7 P. ? MINUARTIOIDES (D. C. prod. 3. p. 375.) stem shrubby, 

 branched ; branches tomentose ; leaves subulate, crowded ; 

 cymes axillary, few-flowered. fj . F. Native of the south of 

 Spain. Mollia minuartioides, Spreng. mant. 1. p. 37. ex Schultes. 

 Lahaya minuartioides, Schultes, syst. 5. p. 406. This is a very 

 doubtful species, being omitted in Spreng. syst. 



Minuartia-like Polycarpaea. Fl. Ju. Aug. Clt. 1826. Pl.^ft. 



18 P. ? DEPRE'SSA (D. C. I.e.) stems herbaceous, depressed, 

 diffuse ; leaves opposite, crowded into something like whorles, 

 wedge-shaped ; stipulas 4-cleft ? flowers terminal, triandrous ; 

 calyx fleshy; petals linear, 4-toothed at the apex. 0. F. 

 Native of the East Indies. Pharnaceum depressum, Lin. mant. 

 p. 564. Lceflingia I'ndica, Retz, ind. p. 48. Roxb. fl. ind. 1. p. 

 169. This plant is certainly neither a Lceflingia nor a Pharna- 

 ceum ; from the stipulas and many-seeded capsule, it agrees more 

 nearly with Polycarpce"a, but differs in the fleshy calyx, and 

 triandrous flowers : perhaps it is more nearly allied to PoUichia, 

 but the calyx in this plant is said to be 5-parted. 



Depressed Polycarpaea. PL depressed. 



Cult. The seeds of the annual species of Polycarpce"a should 

 be reared on a hot-bed early in spring. The perennial and 

 shrubby species being either green-house, or frame plants, 

 require to be kept in their respective places : they are easily in- 

 creased by cuttings under a hand-glass, those of the stove species 

 in heat. 



XI. STIPULI'CIDA (from stipula, a stipula, and ccedo, to 

 cut ; stipulas cut or jagged). Michx. fl. bor. amer. 1. p. 26. t.

LIN. SYST. Triandria, Monogynia. Calyx 5-parted ; lobes 

 oval, with membranous margins. Petals 5, cuneate-oblong, en- 

 tire. Stamens 3, inserted with the petals into the disk or torus. 

 Style short ; stigmas 3. Capsule 1-celled, 3-valved. Seeds 

 few, fixed by funicles to the central placenta. Small perennial 

 dichotomous herbs, native of North America. Radical leaves 

 almost like those of Polycarpce^a Teneriffae, ovate, petiolate ; 

 cauline leaves sessile, opposite, small. Stipulas jagged. Flowers 

 small, tern, terminal. An intermediate genus between Poly- 

 carpon and Polycarpts a, from the sepals being flatfish as in Po- 

 lycarpda, and in the stamens being 3, as in Polycarpon ; but 

 differs from both in the petals and stamens being expressly hypo- 

 gynous according to Richard in Michx. 1. c. ; the genus therefore 

 perhaps ought to have been placed in Caryophyllece.

 Carolina, in sandy arid places. Polycarpum stipulifidum, Pers. 

 ench. 1. p. 111. Pursh, fl. amer. sept. 1. p. 90. Plant gla- 

 brous, setaceous, erect, many times dichotomous.

XII. BALA'RDIA (in honour of M. Balard, of Montpelier, 

 who was the first to detect a new chemical principle called 

 brome). St. Hil. fl. bras. 2. p. 180. 



LIN. SYST. Di-Tetrdndria, Trigynia. Calyx 5-parted almost 

 to the base, permanent ; segments Saltish. Petals none. Sta- 

 mens 2-3-4, inserted in the receptacle. Styles 3, very short, 

 papilliferous inside. Capsule 3-valved, many-seeded ; valves 

 membranous. Seed subovoid, fixed to the central placenta. 

 An annual, branched, dichotomous herb, with opposite, stipu- 

 late leaves, and cymose flowers. 



1 B. PLATE'NSIS (St. Hil. fl. bras. 2. p. 181. t. 111.) leaves 

 linear, about equal in length to the internodes, mucronulate ; 

 cymes branched, many-flowered. . H. Native of Brazil, in 

 the southern part of the province of Cisplatine, near Povo de 

 Canelones ; and in the western part near Pueblo de las Viboras ; 

 also of Buenos Ayres. 



Plate Balardia. PL ^ foot. 



Cult. The seeds of this plant should be sown on a hot-bed 

 in spring, and the plants may be planted out in the open border 

 in the month of May, in any warm dry situation. Not worth 

 cultivating, excepting in a botanic garden. 



XIII. AVE'RSIA (in honour of M. Avers, D. M. P., who 

 has written a dissertation on the Nicoliana Tabdcum, in which he 

 treats of its various qualities). St. Hil. fl. bras. 2. p. 184. 



LIN. SYST. Triandria, Monogynia. Calyx deeply 5-parted, 

 permanent ; lobes thickened in the middle, keeled. Petals 5, 

 inserted in the bottom of the calyx. Stamens 3, inserted with 

 the petals; filaments dilated at the base, joined to the petals 

 and together at the base. Style 1, trifid ; lobes papilliferous 

 inside. Capsule 3-valved, many-seeded ; valves membranous. 

 Seeds fixed to the central placenta, cylindrical. Embryo in the 

 middle of fleshy albumen, not at one side as in Polycarpce a. 

 A trailing branched herb, with opposite stipulate leaves ; young 

 leaves or abortive branches in fascicles in the axils of the -older 

 leaves. Cymes branched, many-flowered. 



1 A. FRANKENIO!DES (St. Hil. 1. c. t. 112.) stems trailing, 

 branched ; leaves lanceolate, bluntish, narrowed into the petiole, 

 pubescent; cymes many-flowered ; segments of calyx obtuse, 

 pubescent ; petals and stamens one half shorter than the calyx. 

 . H. Native of Brazil, on the sandy banks of the rivers 

 Parahyba, Rio Doce, Jiquitiuhonha, Rio de St. Francisco, &c. 

 Flowers white.
